Get a K & N air filter. Don't know exact figures on gas mileage but getting 32 MPG on my 2009 Hyundai Genesis (Hwy mileage) with the new filter. About 4 MPG higher than factory specs and you will probably notice a little more Horse power. Will pay for itself quickly with gas prices now.

The question is, did the car CONTINUE to have the same problem as you drove it multiple times with the gas cap off? I believe that you previously stated that the problem previously occurred only on the first drive after a refill when the gas cap was in place.

I didnt drive it around with the gas cap off did you want me to do that? yes it only happens on the initial start after fueling and it is good after that.

Yes, I'd like to confirm the problem is caused when the gas cap is removed to fuel the car. If the problem continues to exist as long as the fuel cap is off, that would be a pretty good indicator that the fuel vent system is compromised.
Does anyone have any other ideas or possibly a comment on my idea?
